The cute couple looked as radiant as the the sun they were soaking up while taking some time out from, you know, being the hotties known as Zac and Sami. They even wore matching white beachwear. Adorable, right?

Zac is currently in Hawaii shooting Mike and Dave Need Wedding Dates, but from the looks of it, he was happy to take a break from filming to hang with Sami in the sand. In fact, his see-through shirt makes us think he had just been riding the waves!

The 27-year-old actor was first spotted with Sami in Copenhagen, Denmark, in late 2014. The two surely aren't shy about hitting the town (or beach!) together -- back in April, they popped up at the MTV Movie Awards.

Zac's blogger-writer-marketing executive GF recently opened up to Elle about being in the public eye. "It kind of just comes with the territory, and I know there's no really changing that, so you have to just embrace it," Sami told the mag. "I'm not trying to hide anything in my life."
